The development of metal-based redox nanozymes represents a new frontier in pollutant sensing. In this field, designing highly active and precisely regulating their enzymatic activity are key challenges. work, we report the construction copper peroxide@polydopamine (CuO2@PDA) nanozyme with dual enzyme-like activity, mimicking centers laccase peroxidase. Here, CuO2 acts as catalytic center, while PDA serves carrier to prevent aggregation promotes conversion CuII/CuI sites via reduction effect its surface catechol groups complete cycle. As expected, obtained CuO2@PDA exhibits significant laccase- peroxidase-mimetic activities. Moreover, can be systematically switched by adjusting pH temperature. Specifically, dominates near neutral pH, decomposition into Cu ions H2O2 at acidic triggers peroxidase activity. Similarly, temperature-dependent prevailing low temperatures high temperatures. According performance XPS results, possible mechanism has been proposed. Then, based on pH-dependent CuO2@PDA, constructed detection system for isomers organic pollutants, (CC) hydroquinone (HQ). laccase-like enables direct oxidation CC yellow o-benzoquinone, HQ discolors preoxidized substrate generated peroxidase-like CuO2@PDA. selective sensing sensitivity was achieved real water samples. This approach guide design multienzymatic unveil potential uses environmental discrimination.
